Physical Characteristics

Diospyros lotus is a deciduous Tree growing to 9 m (29ft) by 6 m (19ft) at a medium rate. It is hardy to zone (UK) 5 and is not frost tender. It is in flower in July, and the seeds ripen from Oct to November. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required)The plant is not self-fertile. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.

Fruit - raw or cooked[2, 3]. The fruit has an exquisitely rich flavour when it is fully ripe (almost at the point of going bad), but it is very harsh and astringent before then[K]. The fruit may not ripen properly in a cool summer, though if it is frosted it normally develops a very good flavour[K]. The fruit can be dried, when it acquires a date-like flavour[61, 183]. The fruit can also be harvested in the autumn, preferably after a frost, and bletted[183]. (This is a process where the fruit is kept in a cool place and only eaten when it is very soft and almost at the point of going rotten). The fruit of trees in a fairly sunny position at Kew ripens on the tree in most years and produces fertile seed[K]. The fruit contains about 1.9% protein, 0.2% fat, 47.7% carbohydrate, 1% ash[179]. Fruits are about the size of a large cherry, they turn from yellow to blue-black when fully ripe[183]. The fruit is about 20mm in diameter[200].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Sometimes used as a rootstock for D. kaki[183]. Wood - durable, pliable, resists rot. Used for construction, general carpentry etc[74].

Cultivation details

Requires a good deep loamy soil in sun or light shade[200]. When being grown for its fruit, the tree should be given a warm, sheltered, sunny position[K]. It dislikes very acid or wet and poorly drained soils[200]. Dormant plants are very cold-hardy, but the young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun[K]. Dioecious, but the female tree can produce seedless fruits in the absence of a pollinator[1]. It is likely that unfertilized fruits are more astringent than fertilized fruits since this is the case with D. kaki[K]. Plants have a long tap root and are difficult to transplant[200], it is best to plant them out in their permanent position as soon as possible and to give protection overwinter for the first year or two[K]. This species is sometimes cultivated for its edible fruit in Italy and E. Asia, there are some named varieties[142, 183].

Propagation

Seed - best sown in a cold frame as soon as it is ripe[113, 200]. Stored seed requires a period of cold-stratification and should be sown as early in the year as possible[78]. It usually germinates in 1 - 6 months at 15°c[175]. Pot up the young seedlings as soon as they are large enough to handle into fairly deep pots and plant them out into their permanent positions in early summer. Give them some protection from winter cold for their first year or two outdoors. Cuttings of half-ripe wood, July/August in a frame[200]. Layering in spring[200].

And some information about Diospyros lotus and virginia,
they both carry fruits here in Belgium ,and I have
already tasted the lotus. One fruit the size of a tomato
had fallen from the tree and was at an early
stage of rotting, but the rest of it whas very good of taste.

I live in belgium and I am a collector and nurseryman of edible landscaping plants. I have a large collection of diospyros species that produce edible fruit and all fruit very well in my country and carry tasty fruit but I yet have to come across a Diospyros lotus that produce LARGE and VERY TASTY fruit different from the type plant. Does anybody know if such a selected variety exists. There many selections of D.virginiana and many more of D.kaki but so far no known selections of very well fruiting D.lotus.

Diospyros lotus is abundant in the Swat valley of Pakistan, the poor farmers sell it on very low prices then the dealers sell it in the down country cities. Now Lasoona-Society for human and natural resource development and IPRP project is working for its value additions and inhacing income of the mountain people through marketing of Diospyrus lotus.

Whilst I acknowledge that the tree is dioecious, where I live in East London there is a mature tree growing in my friends front garden full of ripe fruit as I write.
I have not seen another one in the area, in fact it is a very rare tree to see in London.
Question: How does it produce fruit?(In grest quantity?) unless this particular one is a self pollinator.
I will examine its flowers next year and prove it to myself!!

Stephen, female flowering D.lotus are able to produce seedless fruit without a male around, but these fruit will be more astringent than fertillised ones (Source of info: Discovering fruit and nuts by S lyle)

indeed, D.lotus is dioecious but as is the case with many (or perhaps most)diospyros species, a female tree will readily produce fruit but without seed(parthenocarpic fruit set).
Nevertheless, in my collection I have a male tree that does set fruit. It has the typical clustered flowers of the male tree(bunches of 3 flowers )but they do develop into mature fruit, albeit smaller than those formed on female trees.
But does anyone know of a variety that has really big fruit (i.e. somewhat like D.virginiana)
